The deep and rewarding purpose necessarily must be separated from the carrying capacity of the world. There are plenty of families with 12+ kids, but this clearly isn't something that would be possible to sustain for all couples. This is a fundamental tragedy of the commons. I feel guilty about even wanting to have two kids at some point due to the climate impact. Everywhere I look I see people having large families without caring. This has to be balanced long term for our species (and others) to survive centuries from now.
